When must expert disclosures be given?

• A. No later than 90 days before trial
• B. At least 60 days before trial
• C. After trial starts
• D. At least 30 days before trial

Answer: (B)

Expert disclosures must be given with enough lead time for the other side to evaluate, depose, and prepare for trial. The standard deadline used here is at least 60 days before trial for initial expert disclosures. This provides a reasonable window for the opposing party to review the expert’s report, consult with their own experts, conduct depositions, and address any challenges before trial.

There can be related timing rules, such as rebuttal experts needing disclosure within 30 days after the other party’s disclosure, or scheduling-order adjustments that push or pull these dates. But the baseline reflected in this context is 60 days for initial expert disclosures.

Why the other timeframes don’t fit as the default: 90 days before trial is a longer lead time that isn’t the standard in this material, 30 days before trial is typically too short for initial disclosures, and giving disclosure after trial would defeat the purpose of having the information available for trial preparation.
